2. Description of the Related Art

Recently, with the growth of communication technology and electronic device technology, various portable communication devices and display devices have been developed. Many people possess personal portable communication devices, and display devices that perform various functions have been installed in many vehicles.

In the case of communication devices, even if the technology is further developed, phone calls and text messages are some of the primary methods to transfer information to another party. Further, phone calls, text messages, and web search are some of the primary methods to receive information.

In particular, a primary method that is used to conveniently transfer information to another party is text message transfer. However, for such text message transfer, a text input process is necessary to prepare a phrase. In special situations, such as driving a car, such a text input process may be dangerous. Furthermore, mistyping may occur during the text input process. Although the size of the display of portable communication devices has become larger, it is relatively smaller than those of other display devices due to the characteristic of the portable device itself. Accordingly, in order to perform text input through such a relatively small screen, it is necessary for a user to concentrate his/her attention thereon, and this may cause inconvenience in use and danger in the special situations.

In order to solve the above-described problem, technology to transfer text by voice recognition has been researched. However, a user's voice is often not completely recognized or is not completely converted into text.

Accordingly, there is a need for technology that enables a user to conveniently send a text message using the display device.

As another example, the server 400 may not be a physically existing server, but may be a web, such as the Internet. Further, the server 400 may be a management server that generates a user profile corresponding to user information received from the mobile device 200 and stores user-related information.

For example, the mobile device 200 and the server 400 may be connected using a wireless LAN method, such as Wi-Fi.

As described above, the mobile device 200 may connect to another mobile device using the cellular communication method to transmit or receive voice calls or data, or may connect to a server using a wireless LAN method to transmit or receive data. Up to now, the message transfer system and the system between the server 400 and the mobile device 200 have been described. Hereinafter, a display device 100 and a mobile device 200, which are included in the message transfer system, will be described.

FIG. 3 is a block diagram of the display device according to an exemplary embodiment. Referring to FIG. 3, a display device 100 includes a memory 110, a detector 120, a display 130, a controller 140, and a communicator 150.

In the memory, a plurality of templates, which are differently set according to the kinds of messages, are stored. The kinds of messages refers to a category that is predetermined for the display device 100 to conveniently transfer messages. For example, the kinds of messages may include a first message for transferring location information of the display device 100, a second message for transferring traffic status information, a third message for transferring estimated arrival time information, a fourth message for transferring weather information, and a fifth message for transferring content information that is reproduced in the vehicle. The content may be reproduced in the display device 100, the mobile device 200, or another content reproduction device (not illustrated) located in the vehicle. The kinds of message may include messages for transferring current user status, passenger boarding information, vehicle speed information, temperature information, and radio channel information that a user listens to.

The template refers to a prescribed form, and may include predetermined phrases and predetermined images.

The different templates are stored in the memory 110 to correspond to the kinds of messages. For example, a template “I'm passing” may be stored in relation to the location information, and a template “The traffic is” may be stored in relation to the traffic status information. A template “I'll be there around” may be stored in relation to the estimated arrival time information, and a template “Today is” may be stored in relation to weather information. Different templates are stored according to the kinds of messages, and one template may be stored to correspond to one message kind. The stored templates and the message kinds may be updated or edited according to a user operation. Further, the memory may store plural pieces of status information detected by the detector 120.

Further, if the display device makes a call, the memory may store call details to be transferred to the server 400. The display device may transfer the call details to the server 400 in real time without storing the call details.

The detector 120 detects different pieces of status information. The status information may refer to the location information of the display device 100, the traffic status information, the estimated arrival time information, the weather information, and the content information that is reproduced. Further, the status information may be current user status information, passenger boarding information, vehicle speed information, temperature information, and radio channel information that a user listens to. The location of the display device 100 may refer to a location that is detected through reception of a GPS signal. The user status information refers to whether the user is driving.

For example, the detector 120 may detect location information of the display device 100 through reception of the GPS signal, or may detect the traffic status information, the estimated arrival time information, the vehicle speed information, the weather information, or the temperature information through storing the information therein or through reception of various information from a server (not illustrated) that can search for the information. The display device 100 may be connected by wire or wirelessly to the electronic control unit 300 of the vehicle. Accordingly, the vehicle speed information may be detected through reception of related information from the vehicle.

The user status information, for example, “during driving,” may be detected at a moment when a user connects the mobile device 200 to the display device 100. Specifically, the user status information may be detected in a manner such that if the vehicle speed information is less than 5 km/s after the mobile device 200 is connected to the display device, “drive standby state” may be detected, and if the vehicle speed information is more than 5 km/s, “drive state” may be detected. The above-described examples are exemplary, and the drive standby state and the drive state may be set according to various standards.

The passenger boarding information may be detected in a manner such that passengers are detected using a detection sensor provided in the vehicle and the passenger information detected by the electronic control unit 300 is transferred to the display device. Further, the passenger boarding information may be detected in a manner such that the display device 100 performs communication with terminal devices carried by the passengers. Further, the passenger boarding information may be manually input by a user and may be stored in the memory 110.

The detector 120 may detect content information that is reproduced in the display device 100. If the content is being reproduced in the mobile device 200, the mobile device may transfer the content information that is being reproduced to the display device 100. If the content is reproduced in another content reproduction device in the vehicle, the display device 100 or the mobile device 200 collects audio data of the content that is being reproduced and transfers the collected audio data to the server 400 through the mobile device 200. The server 400 searches for content information that coincides with the received audio data and transfers the searched content information to the mobile device 200. The mobile device 200 transfers the received content information to the display device 100. Through the above-described process, the display device may acquire the content information that is being reproduced in the other content reproduction device in the vehicle.

The display 130 displays a message transfer screen. The message transfer screen may include an opposite party (i.e., another party) for message transfer, a message kind selection menu, and a text to be transferred. Further, if the mobile device 200 receives a call signal, the mobile device 200 transfers the received call signal to the display device 100. The display 130 of the display device 100 may display sender information of the received call signal. The display 130 may be implemented by at least one of a liquid crystal display, a thin film transistor-liquid crystal display, an organic light emitting diode, a flexible display, and a three-dimensional (3D) display.

If the kind of message to be transferred is selected on the message transfer screen, the controller 140 automatically generates a message through combination of the template and status information, which correspond to the selected kind of the message. If a call is made, the controller 140 controls the communicator 150 to transmit the call details and the location information of the display device 100 to the mobile display 200. The controller 140 controls respective constituent elements of the display device 100 including the memory 110, the detector 120, the display 130, and the communicator 150.

The communicator 150 transfers the message to the mobile device 200. Further, the communicator 150 may transmit or receive various data with the mobile device 200, transfer a user command to the mobile device 200, receive vehicle status information from the electronic control unit 300 of the vehicle, or transfer the user command to the electronic control unit 300.

FIG. 4 is a block diagram of a mobile device 200 according to an exemplary embodiment.

Referring to FIG. 4, a mobile device 200 includes a communicator 210, a memory 220, and a controller 230.

The communicator 210 functions to connect the mobile device 200 to an external mobile device or a display device 100. The communicator 210 includes a cellular communication module (not illustrated). Accordingly, the communicator 210 can transfer and receive a voice call, a video call, or a message with the external mobile device or the server.

Further, the communicator 210 may be provided with a USB connector to be connected to the display device 100 through a USB cable. Accordingly, the communicator 210 can transfer and receive data with the display device 100. For example, the communicator 210 receives a message from the external mobile device. The communicator 210 transfers the received message to the display device 100 under the control of the controller 230. The transfer of the received message may be performed according to a message transfer request command included in a predetermined application of the display device 100 if the application is executed. Further, if the mobile device 200 and the display device 100 are connected to each other, the mobile device 200 may be set so as to automatically transfer the message or the call received through the mobile device 200 to the display device 100.

Further, the communicator 210 receives the message, receiver information to receive the generated message, and the message transfer command from the display device. The message received from the display device 100 is transferred to a receiver according to the transfer command.

The memory 220 functions to store various programs required to drive the mobile device 200 and data. The memory 220 may store the message received from the external mobile device, and temporarily store the generated message that is received from the display device 100. Further, the memory 220 may store inherent information and setting information of the display device 100 and the mobile device 200. For example, the memory may include a ROM, a RAM, or a memory card (e.g., an SD card or a memory stick) that can be detachably mounted in the mobile device 200. Further, the memory may include a nonvolatile memory and a volatile memory.

The controller 230 controls the communicator 210 to transfer a call or a message received from an external device to the display device 100 and to receive the generated message from the display device 100. Further, if a user command input to the display device 100 is received through the communicator 210, the controller 230 performs the corresponding control operation.

Up to now, the display device 100 and the mobile device 200 have been described using the block diagrams. Hereinafter, a method for generating a message in the display device 100 will be described.

FIG. 5 is a timing chart illustrating a method for receiving current status information from a vehicle and a server and generating a message according to an exemplary embodiment.

Referring to FIG. 5, the display device 100 receives vehicle information from the electronic control unit 300 of the vehicle (S510). For example, the information received from the electronic control unit 300 of the vehicle may be vehicle speed information, vehicle outdoor temperature information, vehicle indoor temperature information, and location information. The temperature information may be detected by a sensor mounted on the vehicle and may be transferred to the display device 100 through the electronic control unit 300. The speed information may be detected by a sensor mounted on the vehicle or may be indirectly acquired from the information on the engine revolution measured for engine control and the degree of opening of an accelerator. If a GPS module is mounted on the vehicle, the vehicle location information received from the mounted GPS module may be transferred to the display device 100. In the present exemplary embodiment, the display device 100 may be built in the vehicle, or may be detachably mounted on the vehicle. In an exemplary embodiment, it is assumed that the display device 100 is attached to the vehicle, and in consideration of the error range of the GPS signal, vehicle location information, location information of the display device 100, and the location information of the mobile device 200 are considered to be the same.

The display device 100 may connect to the electronic control unit 300 using a CAN communication method, and all information measured and detected through the electronic control unit 300 can be automatically transferred to the display device 100. The display device 100 may store various vehicle information received from the vehicle, and may display the received information through the display.

The mobile device 200 receives various kinds of information from the server 400 or the web. For example, the various kinds of information may include location information of the mobile device 200, traffic information, and weather information. If the mobile device 200 includes the GPS module (not illustrated), the mobile device 200 may receive the location information of the mobile device 200 through the GPS module. As described above, the location information of the mobile device 200, the vehicle location information, and the location information of the display device 100 are considered to be the same. The traffic information and the weather information may be received from the server 400 or the web. Further, in the case where the content is reproduced in another content reproduction device in the vehicle, the mobile device 200 may transfer the audio data of the content being reproduced to the server 400. The server 400 may search for the content information using the received audio data, and then may transfer the searched content information to the mobile device 200.

The mobile device 200 transmits the received information to the display device 100 (S530). As described above, the various kinds of information may include the location information of the mobile device 200, the traffic information, and the weather information. On the other hand, if the mobile device 200 has map data and navigator function, the mobile device 200 can acquire the estimated arrival time information from the stored map data and navigation application. If the content is reproduced in the mobile device 200, the mobile device 200 can acquire the content information being reproduced. As described above, the mobile device 200 may transfer not only the information received from the server 400 or the web, but also the information acquired by the mobile device 200 to the display device 100. The information to be transferred from the mobile device 200 to the display device 100 may be requested from the mobile device 200 through the display device 100. The detector 120 of the display device 100 detects the kind and status of the information from the received information. The detected information is stored in the memory 110.

Alternatively, at least one of the vehicle location information, the estimated arrival time information, and the content information being reproduced may be acquired by the display device 100. For example, if the display device 100 includes the GPS module (not illustrated), the vehicle location information can be directly acquired from the display device 100. If the display device 100 can perform map data and navigation function, the display device 100 can directly acquire the estimated arrival time information. In the case of the content being reproduced in the display device 100, the display device 100 can directly acquire the content information. If the display device 100, the mobile device 200, and the electronic control unit 300 acquire plural pieces of the same information, the display device 100 may not request the corresponding information from the mobile device 200 or the electronic control unit 300. Further, if the display device 100 acquires plural pieces of the same information, the display device 100 may store only one piece of information in the order of their determined priorities.

The display device 100 prepares a message (S540). The display device 100 stores the information received from the mobile device 200 and the electronic control unit 300 of the vehicle. The mobile device 200 or the electronic control unit 300 of the vehicle may automatically transfer the various kinds of information to the display device 100 at a predetermined time or at a time when a specific event occurs. For example, if the vehicle indoor temperature information is changed after the electronic control unit 300 transfers the vehicle indoor temperature information to the display device 100, the electronic control unit 300 may automatically transfer the changed vehicle indoor temperature information to the display device 100. Further, if the estimated arrival time information is changed, the mobile device 200 may automatically transfer the changed estimated arrival time information to the display device 200. Further, the mobile device 200 or the electronic control unit 300 may transfer the information at predetermined intervals, for example, at intervals of one minute or five minutes, and the display device 100 may periodically request the information transfer from the mobile device 200 or the electronic control unit 300. The detailed message preparation method will be described later.

The display device 100 transfers the prepared message to the mobile device 200. If the display device 100 receives a message preparation completion command or a message transfer command, it transfers the prepared message to the mobile device 200. The mobile device 200 transmits the message received from the display device 100 to the external mobile device (S560).

FIG. 6 is a diagram illustrating current status information detected by the display device 100 according to an exemplary embodiment.

Referring to FIG. 6, different pieces of status information 10 that correspond to the kinds of messages are illustrated. The plural pieces of status information 10 may be detected by the detector 120 and may be stored in the memory 110.

Hereinafter, a method for the display device 100 a to generate and transfer a message without the mobile device 200 will be described.

FIG. 13 is a timing chart illustrating a method for receiving current status information and generating a message according to another exemplary embodiment. The display device 100 a explained with reference to FIG. 13 may include a cellular communication module 151 and transfer/receive a call and a message.

Referring to FIG. 13, the display device 100 a receives various kinds of information from the server 400 or the web. For example, the various kinds of information may be location information of the display device 100 a, traffic information, or weather information. As described above, it is considered that the location information of the display device 100 a and the location information of the vehicle are the same. Further, in the case of reproducing content in another content reproduction device in the vehicle, the display device 100 a may transfer audio data of the content being reproduced to the server 400 to request a search, and receive content information from the server 400.

The display device 100 a receives vehicle information from the electronic control unit 300 of the vehicle (S1320). For example, information that is received from the electronic control unit 300 of the vehicle may be vehicle speed information or vehicle temperature information. The display device 100 a may store various kinds of vehicle information received from the vehicle, and display the vehicle information through the display.

The display device 100 a prepares a message (S 1330). The detector 120 of the display device 100 a determines which status information is provided from the received various kinds of information, and detects the corresponding status information. The display device 100 a stores the status information detected from the mobile device 200 and the electronic control unit 300 of the vehicle. The various kinds of information may be automatically transferred to the display device 100 a at a predetermined time or at a time when a specific event occurs. The message is generated through combination of the stored status information corresponding to the selected status information menu and the pre-stored template.

The display device 100 a transfers the prepared message to the external mobile device (S1340). If the display device 100 a receives the message preparation completion command or the message transfer command, the display device 100 a transfers the generated message to the external mobile device. That is, the display device 100 a may be directly connected to the external device or the server 400. Further, the display device 100 a may be connected to the electronic control unit 300 using the CAN communication method, and all information measured and detected in the electronic control unit 300 may be automatically transferred to the display device 100 a. For this, a more detailed explanation will be made hereinafter.

FIG. 14 is a diagram illustrating a data frame format of CAN (Controller Area Network) according to an exemplary embodiment.

The CAN refers to a vehicle network system for providing digital serial communication between various kinds of measurement control equipment. By replacing the complicated electrical wirings and relays of the electronic components in the vehicle by serial communication lines with intelligence, the weight and the complexity can be reduced. Further, an abnormality which may occur due to an electronic interference can be diagnosed.

The CAN is the standard of multiple master broadcast serial buses for connecting the electronic control unit. Respective nodes can send and receive a message with each other, but are unable to simultaneously send and receive the message. The message is composed of an ID that indicates a priority of the message of 8 bytes at maximum. The devices connected to the CAN normally include a sensor, an actuator, and other control devices. The devices are not directly connected to the bus, but are connected through a host processor and a CAN controller.

Like other network protocols, the CAN protocol includes a physical layer, a transfer layer, an object layer, and an application layer. The CAN may be set with two different message (or frame) formats. A normal frame supports an identifier of 11 bits, and an extension frame supports an identifier of 29 bits.

Referring to FIG. 14, the CAN data frame format includes one-bit start of time field 1405, 11-bit or 29-bit identifier field 1410, one-bit remote transmission request (RTR) field 1415, 6-bit control field 1420, 0-8-byte data field 1425, 15-bit cyclic redundancy checking (CRC) field 1430, one-bit ACK delimiter field 1445, and 7-bit end of frame field 1450.

The start of frame field 1405 indicates the start of frame transfer. The identifier field 1410 is for data that expresses a message priority, and in the case where two nodes simultaneously transfer messages, the transfer order is determined according to the priority of the identifier field 1410. If the RTR field 1415 is 0, it means dominant in the data frame, and if the RTR field 1415 is 1, it means recessive in a remote frame. The remote frame is a frame that is output when the receiver requests data from the transmitter.

The control field 1420 includes one-bit identifier extension bit (IDE) field, one-bit reserved bit field, and four-bit data length code field. The data field 1425 includes data to be transferred. The CRC field 1430 checks error through division of bits of a predetermined section. If ACK slot 1440 is 1, the transmitter sends recessive.

The CRC delimiter field 1435, the ACK delimiter field 1445, and an end of frame field 1450 must be 1 in recessive state.

As described above, communication between the electronic control units becomes possible using the CAN, and the vehicle status information may be transferred to the display device 100 a, such as a head unit (H/U) of the vehicle.

FIG. 15 is a flowchart of a message transfer method of the display device 100 a or 100 according to an exemplary embodiment.

The display device detects different pieces of status information (S1510). The plural pieces of status information may be location information of the display device, traffic status information, estimated arrival time information, weather information, content information that is reproduced through the display device, current user status information, passenger boarding information, vehicle speed information, temperature information, and radio channel information that a user listens to. The detected status information may be stored in the memory.

The display device display a message transfer screen (S1520). If a message to be transferred is selected, the display device combines the corresponding template and status information (S1530). The corresponding template is pre-stored in the memory to correspond to the kinds of messages. The kinds of messages or the stored templates can be edited by the user. The display device transfers the message according to the user's transfer command (S1540).

The message transfer method of the display device according to exemplary embodiments as described above may be implemented by a program and may be provided to the display device.

As an example, a non-transitory computer readable medium, which stores a program to execute detecting different pieces of status information, displaying a message transfer screen, automatically generating a message through combination of one of a plurality of templates that are differently set by kinds of messages and stored and the status information, which respectively correspond to the selected kind of message, if the kind of message to be transferred is selected on the message transfer screen, and transferring the message to an external device, may be provided.

The non-transitory computer readable medium may be a medium which semi-permanently stores data and is readable by a device. Specifically, various applications and programs as described above may be stored and provided in the non-transitory computer readable medium, such as, a CD, a DVD, a hard disc, a Blu-ray disc, a USB, a memory card, and a ROM.
